3 Claims. (Cl. 37-133) The present invention relates to new and usefulimprovements in earth working apparatus.

An object of the invention is to provide an earth working apparatus ofgenerally improved design.

Another object of the invention is the provision of an earth workingapparatus which is vhighly eiicient for scraping, earth carrying andload dumping.

A further object of the invention is to provide an apparatus of theabove character having nuid actuated means for operating a scraping,carrying and dumping member thereof.

Still another object of the invention is to provide apparatus of theaforesaid character which is compact, durable and relatively simple inIn describing my invention in detail, reference will be had to theaccompanying drawings illustrating a practical adaptation-of theinvention, and in which:

Figure 1 is a top plan view of the apparatus in earth carryingarrangement,

Figure 2 is a view partly in side elevation an partly in' section of thesame,

Figure 3 is a longitudinal section taken on line 3-3 of Figure 1 withone section of the bowl in earth dumping position,

Figure 4 is a similar view showing the bowl of the apparatus in earthscraping position,

Figure 5 is a fragmentary longitudinal sectional view showing thedigging elements in extended digging position,

F'Eure 6 is an end elevational View of one of the bowl sections,

Figure '7 is a transverse sectional view through the complementary bowlsection,

Figure 8 is a transverse section taken on line 8--8 of Figure 1, and

Figure 9 is a top plan view of the frame of the apparatus.

With reference to the drawings,V wherein like characters of referencedenote corresponding parts throughout the several views F generallydesignates the frame ofthe apparatus which embodies a rectangular shapedbody section having an elongated draft bar l5 extending forwardly fromthe center of the front transverse frame bar I6. 'I'he rear transverseframe bar I1 is advantageously of channel shaped cross section formedwith a pair of spaced forwardly directed bearing eyes I8. At the medialportion of each side bar I9 of the frame body is provided a bearing 20.A pair of converging bars 2| serve to reinforce the connection of thedraft bar I5 with the body section of the frame. To the forward endofthe draft bar is connected a hitch head 22 provided'with a pluralityof apertures for adjustable connection with a tractor T or othersuitable draft means.

In each of the side bearings 20 is rotatably mounted the innertransversely directed journal portion of an axle crank 23 having-theright angularly directed arm disposed outwardly of the framey and havingeach of a pair of supporting or carrier wheels 24 rotatably mounted onthe outwardly directed spindles thereof. The. journals of these cranksare disposed in transversely aligned position and vare formed, at theirinner ends, with anges forming transversely disposed disks 25 whichserve to support a bowl section 26.

This bowl section embodies apair of approximately semi-circulan endwalls 21' formed integral with or connected to the end edges of anessentially arcuate bottom wall 28 extending transversely of the framebetween the end walls, and from the front of the section to a pointslightly exceeding one-half the extent of the outer edge of each of theend walls. Secured to and extending between the rear portions of the endwalls'21 is a longitudinal bar 29 formed at each end with a webterminating in an upwardly projecting apertured ear 30.' As shown toadvantage at Figures 4 and 6, the forward marginal portion of the curvedwall 28 may be practically straight to form a scraping portion whichterminates in a bevelled scraping edge 3| projecting beyond the ends ofthe end walls.

Mounted to assume complementary relationship with the main bowl section26 is an auxiliary bowl section 32 of reduced segmental size havingapproximately sector shaped end walls 33 whose outer peripheral edgesare formed integral with or secured to the end of a bottom wall 3lextending transversely of l the frame and of arcuate transversecurvature corresponding to that of the outer edges of the end walls. Inthe redu ed ends the end walls 33 are provided with concentricallyarranged apertures 35. To the outer side of each end wall 33 is securedan angle member 3 6 providing laterally directed stop lips positionwithin the wall 34. The apertures 35 are fitted on sleeves 31 rotatablymounted on the crank journals between the disks 25 and the framebearings so thatthe auxiliary bowl section is freely rotatable about theshaft portion of the cranks.

On the forward cross bar I6 are fastened a pair of aligned complementarybearing sleeves 38 having journalled therein a transversely extendingrock shaft 39 formed with right angular crank arms 40 at the ends and acrank arm 4I at its center. The outer end of each crank arm 40 ispivotally connected to the inner end of a longitudinally extendingconnectingv rod 42 bent to form an offset at its medial portion andhaving its rear end pivotally connected to the ear 30 of the bowlsection 31.

To the forward portion of the draft bar i is pivotally connected anelongated fluid containing cylinder 43 having ports 44 and 45 at its endportion and having a reciprocating cylinder 46 operatively mountedtherein. To this piston is connected the inner end of a piston rod 41slidable through a packed opening in -the front of the cylinder andhaving its outwardly extending end pivotally connected with the outerend of the crank arm 4| of the rock shaft. The ports 44 and 45 of thecylinder are connected with a control valve 48 through the medium of apair of nexibleconduits 49 and 50. The valve 48 may advantageouslyembody a rotary plug having passages adjustable to connect theconnecting lines 49 and 50 with either the feed port or the dischargeport of the valve or, to intermediate positions to cut off the fluidsupply. As illustrated at Figures 2, 3 and 4 the control valve 48 may bemounted upon a bracket 5l of the tractor in a position convenientlyoperable from the drivers seat.

At the rear of the frame F, immediately forward of the channel bar I1are mounted a pair of parallel rods 52 extended through the aperturedprojections I8 and apertures in the sides of the frame to supportthereon a plurality of, in the present example three, digging implementsor picks 53. These implements embody iiat elongated bars havingforwardly curved and pointed bottom ends and provided with apertures foradjustable connection with the support rods 62.

To the frame bar I6 is connected, by a hinge connection 54, an elongatedscraper blade 55 extending transversely below the frame and preferablyshaped to provide an arcuate transverse curvature. To this blade areconnected a pair of arcuate arms 56 adapted for pivoted connection withthe side bars I9 of the frame at two longitudinally spaced points forfirmly bracing the scraper blade in its depending scraping position andto allow movement thereof to a forwardly directed elevated in-operativeposition. In the latter arrangement of the blade 55 it is releasablysupported by a finger 51 slidably mounted on the draft bar by a slideyoke 58.

To swing the bowl of the apparatus from its an earth scraping positionas illustrated at Figure 4, the valve 48 is actuated to connect thefluid conduit 49 with thel feed line from a source of iiuid pressure onthe tractor so as to slide the `piston 46 toward the front end of itscylinder.

This movement of the piston retracts the, piston rod 41 and, through themedium of the rock shaft and the connecting rods 42, effects clockwiserotation or swinging movement of the closed bowl sections to dispose thescraping edge 3| thereof in a downward position. As the bowl is thusturned the cranks 23 are also rotated to elevate the carrier wheels 24with relation to the frame and the bowl so that the forward edge portionof the latter is disposed below the lowest' counter clockwise movementwhile such further Y rotation of the auxiliary segmental'bowl sectionload carrying position, as shown at Figure 2, to

32 is restrained by the projecting lips 36 which contact with the sidebars of the frame. This action separates or opens the bowl sections toprovide a substantial gap or opening between lthe adjacent edges thereoffor discharging or and dumping and having operative mechanism which canbe easily and conveniently controlled from a tractor.

It is to be understood that the invention is not confined to thespecific construction, arrangement o'r use illustrated and described andthat considerable modification may be made therein within the spirit ofthe invention as defined by the appended claims. l
